title: Two new steroidal glycosides isolated from the aerial part of Solanum torvum Swartz.
abstract: One novel C-22 steroidal lactone saponin, namely solanolactoside C (1), and one new spirostanol glycoside, namely torvoside Q (2), were isolated from the ethanolic extract of aerial parts of Solanum torvum Swartz. The structures of 1 and 2 were determined by extensive NMR experiments including (1)H NMR, (13)C NMR, DEPT, (1)H-(1)H COSY, HSQC, HMBC and ROESY and HRESIMS to be solanolide 6-O-β-d-quinovopyranoside and neochlorogenin 6-O-[β-d-xylopyranosyl-(1 → 3)-β-d-glucopyranoside], respectively.
